Newbie with daft problem.

I install OpenLDAP following the Quick startup guide. Worked a treat. was
able to add entries, search for entries. Everything was ok. Put line in
rc.local to start daemon on boot.
After rebooting. Did the same search and got no answer. When I used the same
.ldif files to add to the database I was told the entries already exist. So
the database is there but now my search provide no results.
Any ideas?
